[0002] In the stamping production process of parts, the amount of material entering the mold cavity or a specific working area is defined as the inflow. Generating an inflow diagram is a task in the later stage of stamping process design. The main purpose is to connect the design and production links.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] It should be noted that, although the functional modules are divided in the system schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0039] The embodiment of the present invention provides a method for generating an inflow diagram of an intelligent design process. Figure 1 , a first embodiment of a method for generating an inflow graph of an intelligent design process of the present application is proposed. In this embodiment, the method for generating an inflow graph of an intelligent design process includes:

[0040] Step S10, obtaining the blank line data of the part, the blank line data includes a first closed line and a second closed line, the first closed line is the blank line after closing of the part, and the second closed line is the blank line after drawing to the bottom of the part.

[0041] The blank line data of the part is extracted from the digital model data of the part. The blank line data includes the blank line after closing and the blank line drawn to the bottom. The extraction operation can be completed through three-dimensional design software. The extracted blank line after closing and the blank line drawn to the bottom are both three-dimensional closed lines. The closed lines are composed of a number of straight line segments and / or a number of curve segments, which are all set based on the origin of the spatial coordinate system, that is, the centers of the two closed lines coincide with the origin of the coordinate system, and it can be understood that the blank line after closing is outside the blank line drawn to the bottom. If both closed lines are projected to the XOY plane, the projection of the blank line after closing will wrap the projection of the blank line drawn to the bottom. For the convenience of explanation, in this embodiment, the blank line after closing is defined as the first closed line, and the blank line drawn to the bottom is defined as the second closed line.

[0042] Step S20: generating an inflow line according to the first closed line and the second closed line, and generating labeling information of the inflow line according to the inflow line.

[0043] The inflow line is a three-dimensional straight line, and its two endpoints are respectively located on the first closed line and the second closed line. The inflow line is used to mark the position of the inflow, and the marking information is used to mark the specific inflow data of the material at this position. The final generated inflow diagram includes multiple inflow lines, and each inflow line has corresponding marking information. Through the inflow line and standard information, the relationship between the closed billet line and the drawn bottom billet line is established, so that the production personnel are guided to complete the production steps of the parts through the inflow diagram.

[0044] Step S30, generating an inflow diagram of the part according to the first closed line, the second closed line, the inflow line and the annotation information.

[0045] The final generated inflow diagram of the part includes the first closed line, the second closed line, multiple inflow lines and the annotation information corresponding to each inflow line. In order to avoid interference, other digital model data of the part is not included, and the inflow diagram is displayed from the perspective of looking down on the XOY plane. Figure 2 , Figure 2 Schematic diagram of the inflow diagram.

[0046] The embodiment of the present invention has at least the following beneficial effects: by acquiring the blank line data of the part, determining the first closing line representing the blank line after the part is closed, and the second closing line representing the blank line after the part is drawn to the bottom, generating an inflow line according to the first closing line and the second closing line, and further generating annotation information according to the inflow line, so as to determine the specific inflow value according to the annotation information, and finally generating an inflow diagram according to the first closing line, the second closing line, the inflow line and the annotation information. Compared with the inflow diagram in the prior art that requires manual insertion and annotation of the inflow line section by section, the present invention automatically generates the inflow line and the corresponding annotation information based on the blank line after closing of the part and the blank line drawn to the bottom, forming an inflow diagram that can guide production personnel to operate, reducing the process steps of the part process design flow, saving time resources and human resources, and improving the design and production efficiency of the part.

[0047] Furthermore, in this embodiment, the step of generating the annotation information of the inflow line according to the inflow line includes:

[0048] Determine the length of the inflow line and generate the labeling information of the corresponding inflow line according to the length.

[0049] Specifically, the annotation information of each inflow line is related to the length of the inflow line. It should be noted that although the final inflow diagram is displayed from the perspective of looking down on the XOY plane, the annotation information is determined based on the length of the inflow line in three dimensions, rather than the length after projection to the XOY plane. The annotation information represents the distance in space between the two endpoints of the inflow line, that is, the two points located on the first closed line and the second closed line respectively. Based on this distance, the material inflow required for part production can be determined.

[0050] On the other hand, reference Figure 2 The annotation information includes specific inflow data and the relationship between each data and the inflow line. Figure 2 The connecting lines are used as a schematic diagram of the association. The specific form of the annotation information is not limited in this embodiment. The association between the inflow line and the inflow data can also be established using numbers or arrows. The annotation information in the inflow diagram can clearly guide production personnel to obtain the inflow data of each inflow line.

[0051] By determining the marking information according to the length of the inflow line, production personnel can obtain the material inflow data of each inflow line position according to the inflow diagram, thereby completing the production of parts. At the same time, generating marking information also avoids the need for staff to manually measure and mark each inflow line, reducing the process steps of the part process design process, saving time and human resources, and improving the design and production efficiency of parts.

[0052] Further, based on the above embodiments, a second embodiment of a method for generating an inflow diagram of an intelligent design process of the present application is proposed. Figure 3 In this embodiment, the step of generating an inflow line according to the first closed line and the second closed line includes:

[0053] Step S21, discretize the first closed line to obtain a plurality of discrete points.

[0054] Step S22, determining a first intersection point according to the discrete points and the coordinate system, the first intersection point being a position where the inflow line is inserted on the first closed line.

[0055] Step S23, generating an inflow line according to the first intersection point and the second closed line.

[0056] The first closed line is discretized and converted into multiple discrete points after discretization. The distances between adjacent discrete points are equal. The first intersection is selected from the discrete points according to the discrete points and the coordinate system, that is, the first intersection falls on the first closed line, which is equivalent to the endpoint of the inflow line on the first closed line, and is also equivalent to the position where the inflow line is inserted. It can be understood that the number of the first intersection points is equal to the number of inflow lines. After determining the first intersection on the first closed line, the inflow line is generated according to the first intersection point and the second closed line.

[0057] By discretizing the first closed line, the first intersection point and the inflow line are further determined according to the obtained discrete points, so that the inflow line can be automatically generated step by step, the process steps of the part process design flow can be reduced, time resources and human resources can be saved, and the design and production efficiency of the parts can be improved.

[0058] Further, in this embodiment, the step of determining the first intersection point according to the discrete points and the coordinate system includes:

[0059] Determine the feature points that fall on the X-axis and Y-axis of the coordinate system among the discrete points, and the first intersection point includes the feature point.

[0060] Taking each feature point as the starting point, search for discrete points with a projection interval of several preset intervals from the feature point along the first closed line in both directions, and determine them as the first intersection point until the corner position of the first closed line is found. The projection interval and the preset interval are both the distance projected on the X-axis or Y-axis.

[0061] Since the boundary line of the actual produced parts cannot be an irregular curve, the first closed line can be divided into multiple straight line segments or curve segments with the corner position as the boundary. For the convenience of distinction and explanation, the straight line segments divided on the first closed line are defined as characteristic straight line segments, such as Figure 2 The first closed line includes four characteristic straight line segments, and a first intersection point is determined on each characteristic straight line segment.

[0062] Specifically, the feature points on the X-axis and Y-axis of the coordinate system are determined among the discrete points, which are equivalent to the intersections of the first closed line with the X-axis and the Y-axis. The feature points belong to the first intersection points and are used as the starting point for finding other first intersection points on each feature straight line segment or curve segment. Figure 4 , Figure 4 The X-axis and Y-axis are shown in dotted lines, and the characteristic points on the four characteristic straight line segments are marked. Taking each characteristic point as the starting point, the discrete points are searched along the first closed line in the direction of both ends thereof, that is, in the direction of the two end points of the corresponding characteristic straight line segment or curve segment with a preset interval as the step size. Figure 4 The search direction is also indicated by an arrow, and the preset interval is set to 100 mm, for example. The discrete point found is determined as the first intersection point until the corner position is found, that is, the endpoint position of the corresponding characteristic straight line segment or curve segment is found. Therefore, the projection interval of other first intersection points and their corresponding characteristic points is composed of several preset intervals. Among them, the projection interval and the preset interval are both the distance projected on the X-axis or Y-axis, and the angle between the characteristic straight line segment and the X-axis and the Y-axis is determined. When the angle with the X-axis is less than or equal to the angle with the Y-axis, the projection interval and the preset interval of the characteristic straight line segment are the distance projected on the X-axis. When the angle with the X-axis is greater than the angle with the Y-axis, the projection interval and the preset interval of the characteristic straight line segment are the distance projected on the Y-axis. For the curve segment, an approximate characteristic straight line segment can be fitted according to its two endpoints, and the above judgment is made based on the angle between the fitted characteristic straight line segment and the X-axis and the Y-axis.

[0063] In addition, the distance between discrete points should be as small as possible relative to the preset interval, for example, 1 mm, so that when searching for discrete points according to the preset interval as the step size, the discrete points can be found. Even if the position found according to the step size happens to fall between two discrete points, the first intersection at this position can be fitted based on the two adjacent discrete points at this position.

[0064] By determining the characteristic points and determining other first intersection points based on the characteristic points, the insertion position of the inflow line can be automatically determined, thereby supporting the subsequent automatic generation steps of the inflow line, avoiding the need for staff to manually select the insertion position of each inflow line, reducing the process steps of the part process design flow, saving time and human resources, and improving the design and production efficiency of the parts. At the same time, the first intersection point determined based on the preset interval and the projection interval meets the insertion position requirements of the inflow line of the inflow diagram required for part production, improving the accuracy of the automatically generated inflow line.

[0065] Furthermore, in this embodiment, the step of generating an inflow line according to the first intersection point and the second closed line includes:

[0066] A reference plane is generated according to the first intersection point, and the first intersection point falls on the reference plane.

[0067] A second intersection point between the reference plane and the second closed line is determined, and an inflow line is generated according to the first intersection point and the second intersection point.

[0068] For each first intersection, a corresponding reference plane is generated, and the generated reference plane passes through the first intersection. The reference plane is a plane in three dimensions, and the intersection of the reference plane and the second closed line is determined as the second intersection. It can be understood that the number of second intersections is the same as the number of first intersections. In this embodiment, a pair of first intersections and second intersections are the two endpoints of the inflow line.

[0069] By generating an auxiliary reference plane and determining the second intersection on the second closed line, the two endpoints of each inflow line are determined, thereby supporting the subsequent automatic generation steps of the inflow line, avoiding the need for staff to manually select the two endpoints of each inflow line, reducing the process steps of the part process design process, saving time and human resources, and improving the design and production efficiency of parts.

[0070] Furthermore, in this embodiment, the step of generating a reference plane according to the first intersection point includes:

[0071] The direction of the reference plane is determined according to the tangent direction of the first intersection point on the first closed line. The direction of the reference plane is parallel to the XOZ plane or parallel to the YOZ plane.

[0072] A reference plane passing through the first intersection point is generated based on the direction of the reference plane.

[0073] Specifically, the reference plane includes two types: parallel to the XOZ plane or parallel to the YOZ plane. In this embodiment, the direction of the reference plane passing through the first intersection can be determined according to the direction of the tangent of the first intersection on the first closed line, and the angle between the tangent and the reference plane when the reference plane is parallel to the XOZ plane or parallel to the YOZ plane is determined respectively. The direction of the reference plane is determined according to the angle, so that the reference plane and the tangent are as perpendicular to each other as possible. Under ideal conditions, for example, when the tangent is parallel to the X-axis, the reference plane should be parallel to the YOZ plane and perpendicular to the tangent at this time. If the tangent and the reference plane cannot be perpendicular, then according to the standard of making the reference plane and the tangent as perpendicular to each other as possible, a direction with a larger angle between the straight line (without direction) where the tangent is located and the reference plane is selected. After determining the direction of the reference plane, combined with the condition that it needs to pass through the first intersection, the reference plane of the first intersection can be generated. In this way, a corresponding pair of first intersections and second intersections have the same X coordinate or Y coordinate.

[0074] In other embodiments, the direction can also be determined based on the angle between the tangent and the normal vectors of the two types of reference planes. On the other hand, the direction of the reference plane on the entire characteristic straight line segment can also be determined based on the angle between the characteristic straight line segment divided by the first closed line and the X-axis or Y-axis, which will not be elaborated here.

[0075] By determining the direction of the reference plane, the reference plane of each first intersection is further generated, thereby supporting the determination of the second intersection of the other end point of the inflow line in the subsequent steps, avoiding the need for staff to manually make auxiliary reference planes for each first intersection, reducing the process steps of the part process design process, saving time and human resources, and improving the design and production efficiency of parts.

[0076] Further, in this embodiment, reference Figure 5 , the step of generating an inflow line according to the first intersection point and the second intersection point comprises:

[0077] A target line segment connecting the first intersection point and the second intersection point is generated, the target line segment is a straight line segment, and the target line segment is determined to be an inflow line.

[0078] A target line segment connecting the two points is generated between the corresponding first intersection and the second intersection. The target line segment is a three-dimensional straight line segment. Since the second intersection is generated based on the reference plane passing through the first intersection, it can be understood that the target line segment also falls on the reference plane. The length of the target line segment represents the distance between the first intersection and the second intersection in space. The distance can be used to determine the inflow data of the material of the part at this position. Therefore, the target line segment is determined to be the inflow line of the part. Exemplarily, Figure 5 In the figure, a indicates a part of the first closed line, b indicates a part of the second closed line, and c indicates a target line segment as the inflow line.

[0079] By generating a target line segment connecting the first intersection point and the second intersection point, the step of generating an inflow line based on the first closed line and the second closed line is completed, the automatic generation of the inflow line is realized, the process steps of the part process design flow are reduced, time resources and human resources are saved, and the design and production efficiency of the parts is improved.

[0080] Further, based on the above embodiment, a third embodiment of a method for generating an inflow diagram of an intelligent design process of the present application is proposed. In this embodiment, before the step of generating an inflow line according to the first closed line and the second closed line, it also includes:

[0081] The first closed line is lowered to a preset height, where the preset height is the stroke of a blank holder.

[0082] There is a certain height difference between the closed blank line directly extracted by the 3D design software and the drawn bottom blank line, that is, there is a distance at a point in the Z-axis direction, which is specifically the stroke of a blank holder. Therefore, in order to ensure the accuracy of the marking information of the inflow line, before generating the inflow line and marking information, it is necessary to lower the first closed line to a preset height. The preset height is set to the stroke of a blank holder. After lowering the height, the first closed line and the second closed line are close to the pressing surface. This can ensure the accuracy of the generated inflow line and the marking information determined according to the length of the inflow line.

[0083] On the other hand, reference Figure 6 , Figure 6 It is a schematic diagram of the device structure of an inflow diagram generating device in an intelligent design process.
